I don't have her any longer as we had to put her down but my Red Nose Pit, Aurora was the BEST deer hunter I've ever been with. If we were driving into a spot to set up a blind or go for a walk about I'd always take her along for the ride. One, she loved to ride shotgun and watch and two, the dog could SMELL deer real well. I mean like right now! All I had to do was tell her we were WATCHING for deer and man she was at it like no buddies business. I'd watch her for a reaction and sure enough each and every time that she'd pop up into the alert position we'd see a deer with in a few minutes. I never took a road hunting shot so it never panned out but that dog could smell deer a long ways off.
Now, IF you have one in a vehicle or ORV and it's not allowed to run the critters but it can smell them and you know what to look for in the dog's reaction is that cheating? I know it's not violating, already checked.
